Can the hunters be genetic monster versions of the elite aliens? Or could the grunts some how have a type of control over the elites? I mean do the elite aliens REALLY NEED the grunts, (well, besides cannon fodder ) Another question that bugs me is the color system on the aliens. (gold elite, red grunt, ect....) Well are they ranking systems or what. and if so, are gold the best elite type or do they just want to look pretty? On a final note, could there be any covenant that are NOT hostile to humans? You know, a rebel faction or something?

Interesting idea, that there might be sympathizers within the ranks of the Covenant. Something to watch for in Halo 2?
